TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable this valve
allows a small quantity of water to
escape during the heating cycle.
However, if it discharges more than
a bucket full of water in 24 hours,
there may be another problem.
Continuous dribble
Try gently raising the easing lever on
the relief valve for a few seconds
(refer to
on page 13). This may
dislodge a small particle of foreign
matter and clear the fault. Release
the lever gently.
Steady flows for long period (often
at night)
This may indicate the mains water
pressure sometimes rises above the
designed pressure of the water
heater. Ask your installing plumber to
fit a pressure limiting valve.
Warning:
Never replace the relief valve with one of a higher pressure
rating.
Heavy flows of hot water until the water heater is cold - then stops
until water reheats
The gas control
must
be turned off using the gas knob on top of the gas
on page 43). Phone
Rheem Service or their nearest Accredited Service Agent to arrange for
inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater
it may discharge a small quantity of water instead of the
temperature pressure relief valve on the water heater. The benefit is that
energy is conserved as the discharged water is cooler.
